some background info
Allow some final words to the gameplay itself. After selecting a puzzle using the pull down menu below you have to click the image to pop up a window which contains the according game. Now you are able to rearrange the puzzle elements until all is fine. The first element you select is your source and will be exchanged with the second one you click on. To cancel a switch operation simply reclick the flashing source element. Below the puzzle some self explaining status info is dumped. Always have a look on the progess bar as it is bidirectional. This means it becomes smaller whenever well placed elements are taken away. Also use this bar as an indicator in the beginning when searching for a start point.
